RIDING-CULTIVATOR.

Speccaton of Letters Patent.

Patented July 1, 1913.

Application led January 10, 1911. Serial No. 601,785.

To all whom t may concern Be it known that I, JAMES O. KENNEMER, acitizen of the United States of America, residing at Mullin, in thecounty of Mills and State of Texas, have invented new and usefulImprovements in Riding-Cultivators, of which the following is aspecification.

This invention relates to riding cultivators, and it has for its objectstof simplify and improve the construction and operation of this class ofmachines.

In order that a riding cultivator may be successfully use d for thecultivation of various crops, the parts of the device shall be capableof ample adjustment in order that each part may be placed independentlyof other parts in position for most thorough service.

To enable-such adjustments to be effected easily, quickly andconveniently is another object of the invention.

Vith these and other ends in view, which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying' drawings has been illustrated a simple andpreferred form of the invention, it being, however, understood that nolimitation is necessarily made to the precise structural details thereinexhibited, but that changes, alterations and modifications within thescope of the invention may be resorted to when desired.

In the drawings, Figure 1 is a side elevation of a cultivatorconstructed in accordance with the invention. Fig. 2 is a top plan viewof the same. Fig. 3 is a rear elevation.

Corresponding parts in the several figures l are 4denoted by likecharacters of reference.

The frame of the machine includes side bars l, 1, the rear ends of whichare connected with a broad cross bar 2 which may be described asconstituting a platform. The front ends of the side bars are offsetlaterally to form brackets 3, 3 which are secured upon the sides of thetongue or draft member l. The side bars 1, l will be hereinafterdescribed as the inner side bars to distinguish from the Outer side bars5, 5, the rear ends of which are secured upon the front side of thecross bar orplatform 2 and the front ends of which are odset laterallyto form ,brackets 6 secured upon the inner side bars adjacent to thefront ends of the latter. The outer side bars 5 are thus kept suitablyspaced from the inner side bars of the frame, as will be most clearlyseen in Fig. 2 of the'drawings.

The forward end of the frame rests upon and is suitably connected withthe front arch 7, the legs of which 7 are provided at their lower endswith outwardly extending spindles 8 upon which Vexternally screwthreaded sleeves 9 are supported for rotation, said revolving screwsbeing equipped' each with a worm gear 10, as best seen in Figs. '1 and2. The outer ends of the spindles S are connected Yby means includinginclined braces 11 with the rear part of the frame. Mounted upon therevolving screws 9 in engagement therewith are nuts 12 constitutingboxes with which the bifurcated heads 13 at the front ends of thecultivator beams 14 are connected by vertically disposed pivots 15 toenable saidbeams to swing laterally in an approximately horizontalplane. Shafts 1G, which are suitably supported adjacent to the sides ofthe frame, arevprovided adjacent to their rear ends with cranks 17 whicharey within convenientreach of the operator and whereby said shafts maybe rotated. The shafts 16 are equipped with worms 18 meshing with thegears 10, which latter, by turning the shafts may be rotated, thusrevolving the screws 9 and e'ect-ing lateral adjustment of the nuts orboxes 12 with which the front ends of the cultivator beamsare connected.The screws 9 may be of any desired length to'aliord sufficient scope ofadjustment, and the parts will be safely retained in adjusted positionowing t-o the employment of worm gear, as described.

A bar or evener 19 is pivotally supported upon the underside of thetongue 1, and said evener is provided at the ends thereof with dependingdraft bars 20 the lower ends of which are vconnected with the ends ofthe spindles 8 by means including resilient draft links 21 of suitablewell known construction which, when draft is applied to the bars 20,will yield to some extent so as to cause the draft to be transmitted tothe cultivator gradually instead of with a sudden jerky motion.

The cultivator beams 14 are preferably of metallic tubular construction,and in their manufacture ordinary iron pipe of suitable dimensions maybe advantageously em-l ployed. Said beams are providedinterme- `diatetheir ends with sleeves or castings 22 which are firmly secured thereon,saidsleeves being formed with foot rests 23, and with` hooks 24. 'Theinner and outer side `bars l and 5 at each side of the frame serve tosupport a longitudinally adjustable or movable base block 26 carrying asegment rack 27 upon which is fulcrumed a handlever 2S having a stopmember 29"engaging said rack. Said levers, therebeing one at each sideof the machine, are connected with the hooks 24 of the sleeves 22uponthebeams 14 bymeans including flexible elements, such as chains 30 andsprings 31, thus causing the beams to be supported from the levers 23with someV degree ofl resiliency, enabling the said cultivator beams tobe Vvtilted or `adjusted in 'approximately vertical planes by means ofthe levers, the beams being capable of swinging vertically about theaxes of the screws 9.

Aseat supporting frame 32 ispivotally connected with clips or clampingdevices 33 which are adjustably mounted upon the side barsl of thecultivator'frame, said se'atsupporting frame including Irearwardlyextending Iside bars 34 carrying a housing 35 in which a shaft '36having an operating crank 37 is supported for rotation, said 'shafthaving a threaded 'portion 3S engaging a nut 39 extending downwardlyfrom the seat 40 whichis"mounted slidably upon' the housing where itwill be seen that said seat may be "shifted or movedforwardly orrearwardly by simply' turning the screw threaded shaft,

thus disposing the seat Vat the' most `advantageous point for the`operator. The operatorin practice places his feetnpon the foot rests 23,thus enabling him when occasion Shall :demand to depress?thecultivatorbeams' against the tension of the supporting "springs 3l and alsoenabling the beams to be 'moved laterallyfif'itshall be desired to dos'owhile the machine is in operation.

'The'axle of the machineisl composed of the cranks 41 providedat theirlo-werends with spindles uponwhich the wheels'42 lare bearing members 44is right' and left threaded internally'for er'iga'gement with the screwthreaded arms 43, Iand said sleeve is provided with an externalwrench'seat. 46 to enable it to be conveniently'rotated, thus moving the:axle ,cranks in`wardly`or outwardly according to the directionof'r'otation, and

thereby regulating the ldistance between the supporting wheels 42, whichlatter may thus be spaced apart to suit the kind as well as `thecondition of growth of the crop that is ltran"sporting wheels, thusexcluding sand and dirt; said sand boxes are connected by linksorconnecting rods 49 including turn buckles 50 with the downwardlyextending arms 5l `of`a rock 'shaft 52l which is supported foroscillation in suitable bearings upo'n the frame of the machine. Saidrock shaft is provided. with' a hand lever 53 having a'stop'member54adapted to engage a segment rack 55 which is suitably supported upon theframe of the machine for the purposeof retaining the axle cranks vin anyposition to which they may be adjusted by the devices just described,thereby enabling the' entire frame of the machine to be raised andlowered relatively to the support-ing wheels. n

Each plow beam carries at its rear end` a frame or Vcasing 'GO wherein astandardGG having a plow carrying foot is vertically 'adjustable' byvsimple means provided for the purpose. Means are also v'provided topermit the footto swing rearwardlywhen obstructions are encountered, butas these parts "are not'herein claimed,they will not be described indetail. Beam spacing members 85 are also provided, `thesame beingfulcrumed on a supporting member 86 andl connected by links 89 with theT-head 90 of an adjusting lever 91.

Eframeof the -machine may be raised or lo'w-l ere'dwith reference to thesupporting wheels, and the latte] may be spaced at various dis- :tan'cesapart. The plowcarrying standards lmay be'iadjus'ted axial-lyso as topresent,w the blades in such 'a manner as to throw the dirt 1n variousdirections. AVertical adjustment of the-plow carrying standards may alsobe vreadily effected. The entire construction is simple, inexpensive andeminently VAsuitable vfor the purposes for which it is intended.

'Having thus described the invention, what is claimed as new, is

`1. 'In a cultivator, "a carrying frame, sleeves connected with theframe and constituting bearings,crankfaxles having screw tli`reade'd"arms suj'oportefd in the sleeves, said arms beingr'espectn'fely yleft and right threaded, a left and right threadedsleeve disposed intermediate the bearing Sleeves and engaging thethreaded arms of the axle cranks, said sleeve having a wrench seat,transporting Wheels upon the crank axles, and means for adjusting thecrank axles and for supporting them in adjusted position to raise orlower t-he frame with relation to the transporting wheels.

2. In a cult-ivator, a carrying frame having bearing sleeves, crankaxles having right and left threaded arms journaled in Said sleeves, athreaded sleeve engaging the right and left threaded arms and having awrench seat, a rook shaft supported upon the earrying frame and havingarms, members conneeting said arms with the crank axles, and means foroscillating the rook shaft and for securing it at various adjustments toadjust the crank axles.

3. In a cultivator, a carrying frame, a front arch connected therewithand having spindles, eultivator beams connected adjustably with thespindles, sleeves mounted upon the eultivator beams intermediate theends thereof and having foot rests and upwardly extending hooks, basemembers supported upon the frame of the machine and having segmentracks, levers pivoted upon the latter and having rack engaging eat-ches,and flexible connecting members including springs connecting the leverswith the hooks extending from the sleeves upon the eultivator beams.

In testimony whereof I aiiix my signature in presence of two witnesses.
